 1753- 



Erect, mostly pubescent perennial herbs, with 

 ternately compound leaves, and compound 

 umbels of white or pinkish flowers. Bracts of the involucre few and deciduous, or none. 

 Involucels of numerous linear bracts. Calyx-teeth obsolete or small. Petals cuneate, or 

 clawed, those of the outer flowers dilated and obcordate or 2-lobed. Stylopodium thick, 

 conic. Fruit much flattened dorsally, broadly oval, obovate, or orbicular; dorsal and inter- 

 mediate ribs filiform, the lateral ones broadly winged and the wings nerved near the outer 

 margin ; oil-tubes extending only to about the middle of the carpels, conspicuous, I in each 

 interval, 2-4 on the commissural side. [Greek, to Hercules.] 



About 60 species, natives of the northern 



hemisphere, only the following in North America. 



Type species: Heracleum Sphondylium L.

Very stout, tomentose-pubescent, 4-8 high, 

 the stem ridged, often 2' thick at the base. 

 Leaves petioled, ternately divided, very pubes- 

 cent beneath, the segments broadly ovate, or 

 orbicular, cordate, stalked, lobed and sharply 

 serrate, rather thin, 3'-6' broad ; petioles much 

 inflated; umbels 6'-i2 r broad, 8-3O-rayed, the 

 rays stout, 2'-4' long; pedicels 3"-9" long in 

 fruit ; fruit broadly oval, or obovate, 4"-6" 

 long, 3"-4i" broad, finely pubescent, emargi- 

 nate at the summit. 



In moist ground, Newfoundland to Alaska, 

 south to North Carolina, Missouri, Kansas, Utah 

 and 1 California. Master-wort. June-July. 



Heracleum Sphondylium L., of Europe, which 

 is loosely pubescent, with pinnate leaves, has been 

 found in' ballast and waste grounds about the sea- 

 ports. 



18. CONIOSELINUM Hoffm. Umb. Ed. 2, 185. 1816. 



Erect perennial glabrous branching herbs, with pinnately decompound leaves, and com- 

 pound umbels of white flowers. Involucre none, or of a few short bracts. Involucels of 

 several narrowly linear bracts. Calyx-teeth obsolete. Petals with an infolded tip. Stylo- 

 podium depressed-conic. Fruit oval or oblong, dorsally flattened. Carpels with prominent 

 approximate dorsal and intermediate ribs, the lateral ones broadly winged and conspicuous. 

 Oil-tubes mostly 2-3 in the intervals, and 4-8 on the commissural side. Seed-face slightly 

 concave, its back strongly convex. [Greek, hemlock-parsley.] 



About 10 species of the north temperate zone. Besides the following, some 3 others occur in
